How often does the air filter change?
2023-04-19
The air filter element is the same as the mask we wear in haze days. It is mainly used to block dust, sand and other impurities in the air. Although this part is inconspicuous and inexpensive, it plays an extremely important role. Someone has done an experiment before. If you remove the air filter of the car and then drive as usual, the wear of the cylinder is eight times that of the car with the air filter, the wear of the piston is three times, and the piston ring is nine times. Times. In other words, without this air filter, the engine will be scrapped for two or three years. In addition, it also has other hazards. If so many impurities in the air run in and burn with gasoline, it will cause insufficient combustion, residual impurities, and carbon deposits. As a result, the car will have insufficient power and increased fuel consumption, and then enter such a vicious circle, and finally the car will be useless.
Normally, the replacement cycle of the air filter element will be indicated in the manufacturer's maintenance manual. Under normal circumstances, the air filter element is recommended to be replaced once every 10,000-15,000 kilometers, because the blockage of the air filter element will affect the air intake of the engine over time, thereby causing the engine The internal air-fuel ratio changes, thereby affecting the combustion process, causing carbon deposits inside the engine, unstable idle speed, reduced power, increased fuel consumption, etc.
Various situations will be encountered in the actual use of the car. Therefore, there is no absolute standard for the replacement of the air filter, because it depends on the amount of dust and impurities absorbed by the air filter. It is also an air filter. On a vehicle that has been driving on the highway for a long time, it can be used for 30000 kilometers or more before replacing it once; for an off-road vehicle that shuttles between the country and the country, it may be two It will be replaced within months. Of course, these two situations are more extreme. For ordinary urban vehicles, it is more appropriate to replace the air filter every year or every 2 kilometers.
Of course, the time or mileage of the vehicle is only a reference value. The final factor that determines whether the air filter needs to be replaced is whether it has not allowed enough air to pass. The air filter must ensure that impurities in the air are filtered out, and at the same time allow enough air to enter the engine.
What needs to be explained here is that the air filter after working for a period of time is actually more efficient than the new air filter. This is because the air filter has adsorbed those impurities can help it to capture more tiny dust. Eventually, the air filter will affect the operation of the engine because of the accumulation of too much dust. At this time, the fuel economy, power and emissions of the vehicle will gradually deteriorate until you change to a new air filter. One tip: An air filter that looks dirty does not mean that it is no longer working properly, so whether it needs to be replaced depends on the condition of the vehicle.
